Medical Scissors for Paramedics, tuff cuts and EMT or EMS shears, are a types of scissors used by paramedics and other emergency medical personnel to quickly and safely cut clothing from injured people. They usually consist of a plastic handle with a metal blade, which is traditionally bent at about 150 degrees, giving them an unusual appearance as compared to normal scissors, and also a longer "lever arm". The shears were designed exclusively for external use and are not suitable for surgical or invasive procedures. Their rugged construction enables them to cut through strong materials such as car seat belts, leather, and denim, and even thin metal and other hard surfaces. The wide, blunt tip on the shears is designed to slide across skin, minimizing the risk of injuring the patient while cutting clothing.
